摘要 |
The invention relates to an aqueous suspension, which comprises inorganic particles and has dry solids content of at least 20 weight-%. The suspension is produced by obtaining or forming an aqueous starting suspension of inorganic particles, adding a water-soluble silicate and a water-soluble calcium source to the aqueous suspension of inorganic particles, and mixing the suspension, whereby a coating comprising calcium silicate hydrate is formed on at least a part of the surface of the inorganic particles. The suspension, when used for manufacture of concrete comprising Portland cement binder and inorganic aggregates, in an amount of 1 – 12 weight-%, based on the weight of Portland cement binder, increases the hydration reaction speed of the concrete by at least 5 %, compared to a concrete not containing said suspension. |
